Abstract:
A multi-spectral imaging system includes a first light source that emits a first wavelength and a second light source that emits a second wavelength different than the first wavelength. The system further includes a camera having a lens, a beam splitter downstream of the lens and a pair of sensors downstream of the beam splitter. The lens is configured to focus the first and second wavelengths onto separate ones of the sensors, and the beam splitter allows one of the first wavelength or the second wavelength to pass through the beam splitter, and the other of the first wavelength or the second wavelength to be reflected off the beam splitter. One of the pair of sensors is configured to receive the first wavelength to produce a first image and the other of the sensors is configured to receive the second wavelength to produce a second image different from the first image.
